The 26-year-old thinning tresses is something she has come to terms with as she has matured, realising her dream of natural long hair is out of reach due to genetics. “I have a family history of female pattern baldness,” Itsines wrote.

"I can see my hair getting thinner and thinner the older I get."

When she’s not wearing clip-in tresses, Kayla confessed to hiding her hair in a messy bun.

I have had a lot of you girls ask me about my hair!! So here is a fact that I haven't actually ever really spoken about. My natural hair is actually super short. I have genetically really thin hair (my grandma and mum both have really thin hair as does a lot of my family) I often just wear a clip in pony tail when I want long hair. It is something I have come to terms with over the years. I have a family history of female pattern baldness. 😁 Most days, as you would see, I leave my hair in a messy bun with a hair tie and I do nothing with it 😝👵🏼 I know we all have our own little insecurities, and one of mine has always been my hair, but it is just me! I can see my hair getting thinner and thinner the older I get. Yes, of course I'm super conscious about it and Ive tried everything to fix it, trust me. But, at the same time, I am at peace with it and I will not let it rule my life. So instead I focus on being healthy and happy. This is definitely a really difficult thing to do and I know from first hand experience, but it is definitely worth it and you have NOTHING to be shy about, be PROUD. I am sure all of you girls know what I am saying, so lets talk about it.
